Primary Outcomes
Change From Baseline in DAS28-ESR at Week 20
Time Frame: Baseline and Week 20
DAS28 was calculated from SJC and TJC using an assessment of 28 joints, the erythrocyte sedimentation rate (ESR) (milliliter per hour \[ml/hr\]), and Patient's Global Assessment (PGH) of disease activity \[measured on a 0 to 100 millimeter (mm) Visual Analogue Scale (VAS) where 0=no disease activity and 100=worst disease activity\]. DAS28 was calculated using the following formula: DAS28 = 0.56\*square root (sqrt) (TJC28) + 0.28\*sqrt(SJC28) + 0.70\*natural logarithm (ln) (ESR) + 0.014\*PGH of disease activity. Total score range: 0-10, with a higher score indicated more disease activity. DAS28 \<=3.2 implied low disease activity, DAS \>3.2 to 5.1 implied moderate disease activity and DAS \>5.1 implied high disease activity, and DAS28 \<2.6 = clinical remission.
Mean DAS28-ESR Score at Visit 4 (Week 20)
Time Frame: Week 20
DAS28 was calculated from SJC and TJC using an assessment of 28 joints, the erythrocyte sedimentation rate (ESR) (milliliter per hour \[ml/hr\]), and Patient's Global Assessment (PGH) of disease activity (measured on a 0 to 100 mm Visual Analogue Scale \[VAS\] where 0=no disease activity and 100=worst disease activity). DAS28 was calculated using the following formula: DAS28 = 0.56\*square root (sqrt) (TJC28) + 0.28\*sqrt(SJC28) + 0.70\*natural logarithm (ln) (ESR) + 0.014\*PGH of disease activity. Total score range: 0-10, with a higher score indicated more disease activity. DAS28 \<=3.2 implied low disease activity, DAS \>3.2 to 5.1 implied moderate disease activity and DAS \>5.1 implied high disease activity, and DAS28 \<2.6 = clinical remission.
Percentage of Participants With EULAR Response
Time Frame: Week 20
The DAS28 score is a measure of the participant's disease activity. It is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity \[visual analog scale: 0=no disease activity to 100=maximum disease activity\], and ESR. DAS28 total scores range from 0 to 10. DAS28 \<=3.2 indicates low disease activity, DAS28 \>3.2 to 5.1 indicates moderate to high disease activity. A negative CFB indicates improvement. The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of CFB and the level of disease activity reached. Good response: DAS28 \<=3.2 and a CFB \>1.2. Moderate response: DAS28 \<=3.2 and CFB \>0.6 to \<=1.2, DAS28 \>3.2 to \<=5.1 and CFB \>1.2 or \>0.6 to \<=1.2, DAS28 \>5.1 and CFB \>1.2. No response: DAS28 \<=3.2 and CFB \>=0.6, DAS28 \>3.2 to \<=5.1 and CFB \<=0.6, DAS28 \>5.1 and CFB \>0.6 to \<=1.2 or \<=0.6.
Number of Participants With Adverse Events (AE)
Time Frame: Up to 39 months
An AE was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
